Our invention relates to improvements in valves for gas burners,

The object of our invention is to provide a simple valve controlling theflow of gas to a main burner and a simmer burner and in which a fullflow of gas to both burners may be obtained or the flow of gas entirelyout ofi.

7 Another object of our invention is to provide a valve of thischaracter in which the flow of gas to the main burner can be entirelycut oif and at the same time maintain a full flow of gas to the simmerburner.

Another object of our invention is to provide a valve of this characterin which the flow of gas to the main and simmer burners may be drawndown or decreased to reduce the flame simultaneously at both burners.

Another object of our invention is to provide a valve in which the flowof gas tothe main and simmer burners can be simultaneously increased ordecreased to regulate the flame.

A still further object of our invention is to provide a valve of thischaracter in which the same is locked in either the full open or closedposition and yet allowing the free turning thereof sothat it can passfrom any of the other positions through the full open or closed positionwithout stopping at suchposition.

A still further object of our invention is to provide a valve of thistype which is simple in construction and operation and very effective toaccomplish the desired results and having certain details of structureand combination of parts hereinafter more fully described.

Referring now to the drawings I represents a valve housing which asshown is of an elongated form having therein a tapering bore 2 whichextends from the open upper end 3. The lower end of the housing isprovided with a reduced screw threaded end 4 having a passage 5therethrough, the inner end of which communicates with the tapering bore2. Screwed on said reduced end is a regulating valve 6 which governs thedischarge of gas to the main burner, which will be later described. Thisvalve'6 may be of any desired form as it forms no part of our inventionand therefore we will not describe the same in detail.

One side of the valve housing I is provided with an outwardly extendingnipple I externally threaded at 8 and upon which is screwed the cap 9which encloses the operating head III of the regulating valve II. Thevalve II has an enlarged externally threaded portion l2 screwed into theinternal threads I3 of the bore i4. The inner end of the bore I4 istapered to provide a. seat for valve H, as at l5, and communicates atits inner end with the bore 2 of the valve housing I, through passage[6. The opening I is provided with a passage H which communicates at itsouter end with the bore l4 of the nipple 1 and the inner end of thepassage communicates with a passage i8 in the. housing which extendsoutwardly from the bore 2 through the nipple l9 and whereby the bore Mhas indirectly two communications with the bore 2 of the valve housing.The outer end of the nipple I9 is externally threaded at 20 forconnection with the gas manifold 20' and whereby the supply of gas forthe valve housing is obtained for feeding the burners.

The passage l8 has communicating therewith an obliquely arranged passagel8 which communicates with the bore of the housing and whereby gas maybe diverted directly from the main gas supply to the simmer burners.

The valve housing adjacent its upper open end 3 is provided with anipple 2| which is externally threaded at 22 for the reception of acoupling I00. The passage 23 allows the gas to pass from the bore 2 ofthe valve housing I to the simmer burner. Manual adjustment of thesimmer burner is efiected by means of an adjustable screw valve |0|mounted on the coupling I00.

Arranged in the bore 2 of the valve housing is a plug valve 24 of atapering form to snugly fit the walls of the bore as is well understoodin valves of the plug type. The lower end of the valve 24 is providedwith the open ended bore 25 which extends about half way up through thevalve and is provided adjacent its-upper end in one side, with a lateralpassage 26 extending through the periphery of the valve. Extending fromthe upper end of the bore 25 is an obliquely arranged smaller passage 21which extends through the periphery of the plug, these passages beingspecifically shown in Figures 23 and 24 of the drawings. The outerperiphery of the plug valve is provided with a groove 28 which extendsnearly half way through the plug as shown in' bore 29 is a'transverseslot 3|, said slot as shown in Figure 1 being wider on one side of thebore 29 as indicated at 32 than that portion 33 as shown in Figure 21,the purpose of which will be later described. The outer periphery of theplug 24 adjacent its upper end is provided with an annular groove 34.

The upper end of the valve housing opposite the open end of the bore 2is provided on opposite sides with outwardly extending cars 35 and 36,the inner ends of which are cut away at 31 and 38 forming a guide wayfor the'latch member later to be described. Fitting in the bore 29 is acoil spring 39, the upper end of which bears against the latch member40. This latch member as shown in Figure 25 of the drawings comprises acircular body portion having on opposite sides thelugs 42 and 43. Thecircular center portion is of a diameter to fit within the bore 29 ofthe upper end of the plug 24 and bears 5 upon the spring 39. The lug 42carried thereby on the main burner.

32 in the upper end of the plug and is free to move up and down underthe tension of the spring. The body portion 4| of said latch is providedwith an upwardly pressed nipple 44 forming a bearing for the valveoperating rod 45.

The valve operating rod 45 is provided at its inner end with adepression 46 to receive the nipple 44. The valve rod 45 on opposite sdes is provided with outwardly extending lugs 41 and 4B, which enter theslots 33 and 32 of the valve plug 24. The lug 41 is of a size to snuglyfit the.

slot 33 while the lug 48 is of a larger size to fit the slot 32 wherebythe valve rod is held in the valve against rotation yet is free to beforced inwardly longitudinally thereof against the tension of the spring39. The spring bears against the circular portion 4| of the latch memberand the same is normally held in its outward position as shown in Figure2 of the drawings. In order to hold the valve operating rod againstoutward movement beyond the slots in the valve plug I provide a cap 49which is of a saucer shaped form having on opposite sides the outwardlyextending ears 59 and 5| to fit on the cars 35 and 36 of the valvehousing and secured thereto by means of screws 52 and 53 whereby the capis held in the position shown in Figure 2 of the drawings. It will beseen by this structure the valve rod 45 is held in position and the ears41 and 49 carried thereby engaging the under face of the cap the same isprevented from being forced outwardly by the spring 39 so that the lugswill not disengage from the slots in the plug. One side of the cap 49 iscut away as indicated at 54 which together with the cut away portions 31and 38 of the ears 35 and 36 form the slot which in combination with thelatch member 40 forms a snap latch for holding the valve in its severaladjusted positions. The wall 55 of the cap 49 extends below the ears and5| serving as a stop to engage the lug .43 of the latch member and holdthe valve in its two extreme positions. It will be seen that the lug 42is of a length to pass on the inside of the wall while the lug 43engages the edge thereof.

. The outer end of the valve stem or rod 45 is cut away as indicated at56 so as to fit a correspondingly shaped slot in the operating handle 51whereby the same is held thereon against rotation. The handle is heldthereon against longitudinal movement by the set screw 58.

The device is.especially designed for burners in'which there is a mainburner 59 and a simmer burner 60 within the same, although the exactlocation of the burners relative to each other do not form a part of theinvention as they could be arranged side by side, it being understoodthat they should be in such relation that the simmer burner will bebelow the cooking utensil placed In Figure 27 we have shown onearrangement of the, burners. The gas supply manifold 20' as shown,supplies gas to the valve housing I through the nipple l9. The nipple 4of the housing and its valve 6 extend into the mixing tube 6| of themain burner 59 while the nipple 2| and its valve extends into the mixingtube 62 of the simmer burner 60.

When the valve plug 2 is in the position shown in Figure 4, the opening26 is opposite the solid wall of the bore and the gas to both burners isentirely cut ofi. When in this position arm 43 of the latch member 40 isin engagement with the wall 54' or station dot the cut away 54 and isheld in said position, Turning the plug counter clockwise by the handthe arm 43 of the latch s moves with the same being outwardly springpressed by the spring 39. When" the arm 43 reaches the slot the springforces the latch outwardly at wall 63 of station 0 into the cut awayportion 54 of the cap and snaps indicating the valve has reached anotherposition. When the plug valve is in this position gas passes through thepassage l8 from the manifold 20 and from said passage through thepassage I! to the cut away portion not the plug 24. When the plug is inthis or full simmer position this cut away portion is also incommunication with the passage 23 leading to the simmer burner and afull flow of gas thereto is obtained. The opening 26 in the plug isopposite the solid walls of the bore of the V housing and no gasis'passed to the main burner.

Continued turning of the valve in a counter clockwise direction causesthe arm 43 to strike the other end or wall 64' at station E of the cutaway portion of the cap 49 and is held against further counter clockwisemovement. When in this position the opening 26 in the plug is oppositethe main gas supply passage is and a full flow of gas passes through thehollow valve out through bore 25 to the passage 5 to the main bumer. Thecut away portion 2Q in the valve plug is of such a length that when inthis position it is also registeringwith the passages 18' and 23 and afull flow of gas is passing to the simmer burner.

By depressing the operating handle the latch member to is movedlongitudinally in the valve and the arm as is brought in beyond the wall64 of the cut away portion 54 of the latch and which allows of acontinued counter clockwise movement of the handle and plug until thearm 43 strikes the wall 55 at station A of the extended portion of thecap. When the plug has reached this position the opening 26 in the plugis opposite the passage it and gas can pass from the main gas passage itthrough passage ll and through passage to and opening26 to the hollowplug valve and from there through bore 25 and passage 7 5 to the mainburner. Continued anti-clockwise movement of the valve stem graduallycloses the plug inlet 26 to inlet l8 but at the'saine time graduallybrings inlet 26 into communication with needle valve controlled by-passpassage l6, and until plug inlet 26 is closed to direct com municationwith inlet l8 and takes it supply of gas for the main burner throughby-pass passages l1 and it. The flow to the main burner is thusgradually reduced to a minimum. During this movement flow of gas throughpassages 18 and 1.8, cut-away portion or groove 28' and outlet passage23, to the simmer burner, is gradually reduced by gradually closingcommunication between groove 28 and. passage 23. At the same time (andbefore this communication has been shut off and the simmer extinguished)the passage 21 extending through the wall of the hollow plug valve intothe bore 25 thereof is brought into, register with the simmer outlet 23.Thus, as the flow of gas to'the simmer is gradually shut oiiE throughthe'groove 28 in the plug, a correspondingly decreased supply of gas ismade available from the supply going through the bore 25 of the plug tothe main burner. This uniform and gradual adjustment of flow to bothburners is made possible by the arrangement 01' passages mentioned andby reason of the fact that the outlet of passage 21, is suflicientlyclose to the adjacent end of cut-away portion or groove 28, that theportion or area 15 of the plug separating the passage 21 and groove 23,is not of sufllcient width to at any time close passage 23, and becauseinlet passage 26 will continue to supply gas direct to the simmer burnerthrough inlet passage 26,.

bore 25 and outlet passage 21, until communication is had throughby-pass passages 16 and i1, bore 25 and simmer outlet passage 21. Theimportance of and necessity for passage 21 is apparent. x

In turning the handle and valve clockwise the arm 43 moves until itsnaps intothe cut away portion 54 adjacent the wall 64 at station 3indicating the full open position giving a full supply of gas to themain and simmer burners. The continued clockwise movement of the handlebrings the arm 43 of the latch 40 in engagement with the wall 63 of thecut away portion '54, at station C of the capand stopping the movementtherein. This is the position with a full flow of gas to the simmerburner. In order to continue the clockwise movement of the valve by thehandle, the

handle is forced inwardly forcing the latch 40 inwardly until the arm 43is beyond the lower end of wall 63 and the valve can be turned, untilthe arm 43 strikes the extended end or wall 54 at station D of thecap149. This brings the valve to a full closed position for bothburners.

By depressing the handle and holding it against the tension of thespring the valve can be turned to any of the before described positionswithout stopping at any of the intermediate positions. The same is truein both counter-clockwise and clockwise movements.

It will be seen from the foregoing that when the plug valve has beenmoved to station A by manipulating the handle 51, and with an equalvolume of gas flowing to both the main and simmer burners, underbalancedpressure, the heighth of the flames of the two burners will bethe same. At this position the volume of the gas flowing to bothburners, as well as the heighth of the flames of these burners pan beregulated to and set at any'desired heighth, below maximum, by means ofthe regulating valve II.

It will be readily understood that whenever the housewife desires tocook with or heat a considerable quantity of liquid the center simmertains very little liquid, use of the main burner is desirable becausethe flame is distributed over a considerable area and consequentlydanger of scorching the utensil or its contents is lessened. From theforegoing it will be seen that gas is simultaneously delivered to thesimmer from both of two different sourcesand independently from thesetwo sources. Also that the regulating valve ii automatically regulatesthe amount of gas which flows to both the main and simmer bumers whenthe valves have been rotated to lowflame simmer position.
